Hello everyone.
So last week I've bought a used a4 b8 3.0 tdi (240hp) manual quattro. It's a 2008 model with 230000km on the clock. The hood and front mask have a few stone chips but nothing major and not very noticeable. The chassis is from S line so its 3cm lower from the factory. It also came with 19" rims that are usually mounted on RS. The second set of rims (17") are for winter. The interior is very well preserved and looks like new. On the test ride no issues are immediately noticed. As I dig deeper into the car inspection the engine warning light came on. The seller called a friend to hook it up and check what the error is about. It turned out to be and idle sensor on the fuel pump. The cable itself was visibly damaged and was literally held by two threads. He then said that some time ago mice came in the engine bay and ate two cables that they later repaired. One of repaired cables was the one that was now causing problems. I also noticed the battery was a bit weak. After a while we agreed on a price and I drove off. Car runs smooth and ride is comfortable. On the way home I've noticed that the engine temp never got past 80°C. That's something I didn't notice before since it didn't had time to warm up.
Fast forward to next day.
After going back from work the DPF filter error pops up. So after coming home we hooked it up to friends pc and noticed that there are quite a few errors that need addressing. The most important ones:
00256 a/c - upon pressing the ac button the red light is lit only while the button is pressed. I yet have to check the sensor and if there is any pressure in system.
00457 Control Module for Network (J519): No Signal/Communication - no solution for this one atm
P063800 throttle body - This was clogged up and some teeth at WOT position were nearly non existing so I've replaced this. The most likely reason for this IMO is that the thermostat hasn't been working for a while so the economy was rubbish which clogged up a lot of stuff and now it needs a thorough cleaning. Also the default position for throttle body is open. Which means when the residue solidified it had to move from that position. Now the worn out teeth make sense. Pic below.
So after replacing throttle body we went to another friend to perform the regeneration. Car at this point has flashing glow plugs and in in limp mode. The attempt to perform regeneration was unsuccessful and it constantly got aborted for "safety reasons". We're aware of non functioning thermostat and the replacement has been ordered. However further investigation showed up another error that no description. U1008 00 [039]
I've found some info that points toward transmission? No further clues at this point. So the regeneration failed and I limped back home. We'll either do the regeneration somehow or start gutting it. If anyone has any info that could be useful ... I also wonder how much HP can stock clutch handle since I plan to chip tune it?
On the long run I plan to ditch the egr, dpf and clear the muffler for better flow.
